Let's follow this process

  • Take a glass with about 100ml of water and add a few crystals of Potassium Permanganate.
  • Now take another glass with 90ml of clear water and add 10ml of solution from the first glass. 
  • Then from this solution, add 10ml of solution to another glass containing 90ml of water.
  • Continuing this process a few more times will result in a series of glasses with reducing intensity of purple colour.

This activity shows that matter is made up of particles that are tiny. This shows that Potassium Permanganate has millions of tiny particles which keep on dividing on each dilution.
